Abstract: 구강 케어 장치(10)는 잇몸 조직에 압축 공기의 버스트 또는 액체의 버스트를 인가함으로써 잇몸 조직에 순간적인 힘을 인가하는 힘 생성 모듈(52), 순간적인 힘이 인가된 후에 시간 경과에 따라 잇몸 조직으로부터 복수의 광학 신호들을 획득하는 센서(28), 복수의 광학 신호들의 분석에 적어도 부분적으로 기초하여, 건강 파라미터(예를 들어, 잇몸 조직의 염증)를 정량화하는 컨트롤러(30)로서, 건강 파라미터는 잇몸 조직이 힘의 인가에 대해 회복하는 데 걸리는 시간의 양에 적어도 부분적으로 기초하는, 상기 컨트롤러(30), 및 정량화된 건강 파라미터에 관한 정보를 사용자에게 제공하는 피드백 모듈(46)에 의해 사용자의 잇몸 조직의 건강 파라미터를 평가한다.
